Hi, just thought I'd make a small correction, you are in fact making ferrite+cementite, also known as coarse pearlite (at a temperature just below the eutectoid temperature) not just ferrite. Thanks for the post.

Hi thanks for the project, I just had a question on the gate drive stage 2, you added a second capacitor on the circuit as C2 but it doesn't have a value, and in the Eagle schematic it isn't even mentioned. So I was a bit confused, thank you!
